A person is facing problem with his/her digestive system or having problem about not able to digest the food means he/she is suffering from Lactose intolerance. To start with the simple, basic information let us understand what it is. Lactose is a carbohydrate or a sugar that is commonly found in dairy products as well as milk. Individuals become intolerant towards lactose because their body is finding a hard time in digesting dairy products and milk sugars. The results are diarrhoea and abdominal pain and this is called a case of lactase deficiency.

Casein is a protein in milk that makes up about 80% of a cow’s milk. Presence of this chemical makes the immune system stronger and trigger muscle growths. It also has an amazing amino acid structure. However, the same chemical is known as a slow-digesting protein which leads to allergies and sensitivities generalized as Casein Intolerance.
Casein Intolerance is a severe negative reaction of the immune system to the protein which may lead t illness and even death. Upon reaction, the body releases Immunoglobulin E or IgE, according to livestrong.com. Moreover, chemicals including histamine are included in the production of antibodies which is pointed out as the main reason for the allergic reaction. This Casein Intolerance is common to children and adult, either consuming a commercial dairy product or even breastfed. Symptoms include itching, abdominal pain, nausea, diarrhoea, fainting or even anaphylaxis.

Lactose intolerance symptoms can show up anyone at any age. Babies can exhibit lactose intolerance and need to be given special formula made from soy or goat’s milk. Adults who are intolerant to products containing lactose experience uncomfortable symptoms. Intolerance to milk and dairy products is not life-threatening. It can be a huge inconvenience when one has to do without milk, cheese, yogurt, ice cream and other dairy products in their diet. There is no cure for those who have lactose intolerance but there are ways to reduce or eliminate the symptoms.

A digestive disorder, lactose intolerance is a common occurrence for people when they face the difficulty to digest complex sugar substances that are present in the form of milk especially from cows. Lactose the complex sugar elements affects those with a defect in their system as they do not have the enzyme lactase to ingest the substance. Without lactase, the body system is unable to break down the substance into er pieces that would convert it into a much easier process to be absorbed.

Before we discuss the symptoms and the causes of casein allergy, we must first understand just what casein is. Casein is a derivative of the Latin word for cheese, ‘caseus.’ It has a wide range of uses from that of being found in matches where it is used as a binder, to additives in our food, and being a large factor within the composites of cheese. It forms the greatest percentage of the total proteins found in cow milk, (80%) and within human production of milk it comprises anywhere between 60 to 65 percent of total proteins produced. Broken down further, casein provides crucial elements to the body such as carbohydrates, amino acids, phosphorus and calcium.

Milk allergies are usually related to cow’s milk, though usually any childhood milk allergies are gone by age three. However, sometimes these can last a lifetime and begin in early childhood. In fact, the allergic reaction to milk usually happens within minutes or might not occur for up to four hours, lasting up to a full day. More severe reactions can result in a shock reaction which requires emergency care. Regardless of the reaction time, a milk allergy does not necessarily have to be as a result of drinking milk as it can come from any type of milk product or food. In some cases, the reaction does not occur until there has been a substantial build up over time of the milk proteins. It can happen through varied forms, including drinking and eating, but also skin contact with a milk product, something that has been in contact with a milk product or someone who has had a milk product and still has remnants on their skin or lips.

Food allergies are usually exaggerated types of immune system responses that are triggered by specific foods. Normally, the immune system works to defend the body against possibly harmful types of substances, toxins, viruses and bacteria. However, some people have defence reactions against certain foods, causing the body to produce immunoglobulin type antibodies to fight off the alleged invader. Though many have intolerances towards foods, food type allergies are not as common. In fact, a genuine food allergy also produces histamines that cause the body to react quickly to the allergen (s).
